Although no two Sulfur Dioxide Loading solutions will be identical, the product itself determines much of the critical design criteria that will ensure that optimum safety and productivity can work together in harmony. 

What is Sulfur dioxide? sulfur dioxide is the chemical compound with the formula SO₂. It is a toxic gas responsible for the smell of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of fossil fuels contaminated with sulfur compounds. Sulfur dioxide has a pungent smell like nitric acid. Sulfur dioxide is also referred to as Sulfurous anhydride, sulfurous oxide, or refrigerant gas.  In the United States, Sulfur Dioxide is a “tight-fill” (closed-loop) loading operation and is loaded into rail cars via 3” chemical hoses or 316 stainless steel loading arms. 

Sulfur Dioxide, if not handled properly can cause serious injuries and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, fall prevention is essential, not only for safety but increases throughput.
